DNA Extraction | Science

Aim: To extract DNA from kiwi fruit 

Equipment:

- Kiwi fruit 

- knife (to cut the kiwi fruit)

- Sand 

- Ethanol 

- Beakers

- Water 

- Heat Mat

- Bunsen Burner

- Test tube 

- Dishwashing liquid 

- Sandwich bag 

- Tripod

- Cloth 

- Spatula 

- Gauze Mat

- Glass rod

Method: 

1. Squish kiwi fruit with sand with water and pour through the cloth to collect the juice in the beaker. 
2. Use the beaker to warm the water, pour juice into the test tube with 2 drops of dishwashing liquid and rest in warm water. 
3. Add Ethanol, watch the DNA separate and collect with a spatula. 

Result: 

Discussion: The Dishwashing liquid separate the walls of the DNA cells. When we added the ethanol it separated the DNA layer from the kiwi fruit and it floated at the top of the tube.
